Localized shear generates three-dimensional transport

Understanding the mechanisms that control three-dimensional (3D) fluid transport is central to many processes including mixing, chemical reaction and biological activity. Here a novel mechanism for 3D transport is uncovered where fluid particles are kicked between streamlines near a localized shear, which occurs in many flows and materials. This results in 3D transport similar to Resonance Induced Dispersion (RID); however, this new mechanism is more rapid and mutually incompatible with RID. We explore its governing impact with both an abstract 2-action flow and a model fluid flow. We show that transitions from one-dimensional (1D) to two-dimensional (2D) and 2D to 3D transport occur based on the relative magnitudes of streamline jumps in two transverse directions.Comment: Copyright 2017 AIP Publishing.

High spatial resolution 100 micron observations of the M83 bar

A program of high spatial resolution far-infrared observations of galaxies using the Kuiper Airborne Observatory (KAO), was conducted to better understand the role of star formation, the general interstellar radiation field, and non-thermal activity in powering the prodigious far-infrared luminosities seen in spiral and interacting galaxies. Here, researchers present observations of the central region of the well-known barred spiral M83 (NGC 5236). The resultant channel 3 scans for M83 and IRC + 10216, after co-addition and smoothing, are shown. These data show that M83 is extended at 100 microns compared to a point source. A simple Gaussian deconvolution of the M83 data with the point source profile from IRC+10216 gives a full width half maximum (FWHM) of about 19 seconds for M83. By comparison with IRC+10216, researchers obtain a flux for the unresolved component in M83 of about 110 Jy. This is about 1/6 the total flux for M83 (Rice et al. 1988) and about 1/2 the PSC flux. The M83 and IRC+10216 profiles in the cross-scan direction (SE-NW) were also compared, and show that M83 is extended in this direction as well, with a width of about 18 seconds. A comparison of the different channel profiles for M83 and IRC+10216 shows that there is an asymmetry in the M83 data, in that the maximum in the profiles shifts from southeast to northwest as channel number increases. This corresponds to the extension in the bar seen in the CO data. Thus the far-infrared emission in the central region of M83 tends to trace the CO bar. The new 100 micron data is also compared with previous H alpha observations from the literature, to determine how well the far-infrared traces the stellar structure, the star formation as measured by H alpha, and the optical colors

The Synthesis Of 2,6-Diamino-2,6-Dideoxy-D-Galactose.

The objectives of this research problem were divided into several parts. The first objective was to develop a practical method of preparing 2,6-diamino-2,6-dideoxy-galactose. A second objective was to investigate the derivatives of benzyl-N-carbobenzoxy-α-D-galactosaminide. FInally, the third objective was to lay the groundwork for another possible route for the synthesis of 2,6-diamino-2,6-dideoxy-galactose other than the uronic acid route

Neoliberalism and Public University Agendas: Tensions along the Global/Local Divide

Over the last decade, internationalization efforts have accelerated at leading postsecondary institutions in North America and elsewhere, with universities now aggressively competing for the most talented students worldwide. With the focus on recruiting international students, one of the major attendant objectives has seemingly been a social-justice-oriented agenda on tackling pressing global issues; the local has indeed become the global. However, not everyone is ostensibly benefiting from this new global focus. For some, their local issues and conditions are increasingly precarious and nonprioritized in institutional and broadening neoliberal governmental agendas. In the Canadian context, various Indigenous and low-income racialized communities, youth in particular, face multiple implications of this reality. For these communities, secondary school completion and postsecondary educational attainment are decreasing, while incarceration rates among the youth are significantly increasing. In this viewpoint paper, we briefly highlight two localized program examples, sharing our experiences as educators, and call for a constructive dialogue regarding how universities’ social justice agendas can better work for all people, both locally and globally

Building bridges? An evaluation of the costs and effectiveness of the separated parents information programme (PIP)

The Separated Parent Information Programme (PIP) is the first nationally available parent education programme for parents involved in litigation over contact and residence in England. The programme is a Contact Activity, introduced by the Children and Adoption Act 2006 as an additional tool for courts to facilitate contact. PIP is a four hour group programme for parents referred by the court. Both parties, i.e. the applicant and respondent, are required to attend the programme, but former couples attend separate groups. The groups are designed to include both men and women. The aim of the programme is to encourage parents to focus on children’s needs and perspectives. The programme is delivered by trained providers from mediation, counselling or contact services backgrounds
